I liked that this was a sustained release protein powder and that was something that I wanted to use before each of my morning workouts. I usually mix a scoop or two of this powder with just a little bit of water and some dry oat bran which mixed together quite well. The macros of this protein powder fit in perfectly with my diet and this kept me full for the duration of my workouts.

Superb filling protein blend, strawberry is ok it really was enjoyable in my green shakes and not overpowering. Not a sweet protein but that's a good thing Im no fan of that I prefer even flavoring and the fact that the sodium, carb and fat are useful. Definitely helps me stay on my diet and makes a difference too as far as convenience and bang for the buck

This is an outstanding product. The nutrition facts are great for someone who is trying to bulk up on muscle but cut down on fat. It mixed great with water or milk. I made protein pancakes too and my entire family enjoyed them. No complaints at all with this one. One of the better tasting cookies and cream flavors I've tried.

A big thank you goes out to Emergency and Nutrabolics for letting me try out ISOBOLIC!!!
This was my first time trying this protein.
I am not a real fan of Strawberry proteins, they usually taste off!!!
I mix mine with 2% milk in a small personal blender. It tastes just like my favorite ice cream from cold stone! I used one scoop with 8 oz milk. I also used it as a meal replacement & muscle recovery drink. I was worried this wouldn't taste good but I was shocked at how good it was. It's very good. I also added some fruit to the blender from time to time. I'd recommend this if you love cake batter ice cream.
So the BOTTOM LINE!!!!!
This protein did in deed help with recovery time and kept me full!!!
I did enjoy the taste and didn't have any stomach issues at all.
Mixed up fine in a shaker also...
So yes!!!!! I would buy this....

It is no exaggeration to say that Isobolic has a great profile. 25g of high quality protein blend that also contains additional BCAAs and Flaxseed powder. Tried the rich Chocolate flavor which is smooth, creamy and thick when mixed with milk. Pro-oats with Isobolic were delicious too. This is a premium protein made from high quality ingredients and no compromises. I recommend it to all looking for a Chocolate blend.

Vanilla

Isobolic vanilla is a good protein powder to use as a mid meal snack or a preworkout shake. It mixes in fairly easily no matter how you decide to use it. If your looking for a vanilla flavor that taste sweet like ice cream, this isnt the one for you but if your looking for a vanilla flavor that is simple tasting and is versatile in regards to how it can be mixed, go ahead and pull the trigger on this one. The price point is $75 for 73 servings but right now (current time) it is 20% off to help ease with cost. Overall, I would order the Isobolic protein powder again because the macros are solid and makes a useful midmeal or preworkout meal but I would get around to trying the other flavors first to see how they taste before giving the vanilla another go around.

Vanilla

Whenever I look a reviews, no one ever seems to comment on vanilla. It's always the best go to flavour as it's the plainest you can generally get. Nutrabolics hit the nail on the head with this one. I'm addicted to the drink.i would only drink If my body could handle drinking it, instead of the four L's or water per day. (And my bank account)

Great, easily digestible protein. Pretty sweet with water but really shines when mixed with milk (just like a rich choc milkshake)works great with oatmeal. A great profile tops off this supplement as a top choice for anyone.

IsoBolic has a really natural sort of banana flavor. I found it easy to regularly eat in oats, shakes, etc. The fact that it's a banana flavor makes for easy integration into recipes (muffins, cookies, breads, etc.) without totally killing or overpowering the flavor of anything else.
Relatively minimal fats and carbs meant I could stay within my caloric allowances in those areas while filling in some protein when needed. It might not be the most fat/carb light protein supp out there but for most I think this would be a great option

Picked up a 5lb tub of this from a local shop. Nearly completed it but gave remaining approx. 10 servings away.
Flavor: 8/10 Cinnamon oatmeal was quite good. Was not overwhelming cinnamon flavor, just right. Occasionally looked forward to drinking.
Mixability 10/10 Had zero issues with this. Mixed well, no clumps after only a few shakes and did not need a grate to assist in mixing.
Ingredient profile 5/10 Protein blend which is a plus. 81% protein per scoop which is also excellent (low carbs and fats). Lost points for additions of isolated amino acids. This should not be happening for any protein products and makes me question the actual protein per serving.
Value 6/10 for a protein blend this cost me more than comparable protein blend brands. Additionally should have been considerably cheaper considering the amino acid additions.
Efficacy/Other: 3/10 I feel this worked about as well as many of the other protein product blends I've tried thus far, did not excel or hinder workouts and weight management. However, about half way through I started getting GI upset approx 15min after consumption. Continued until I stopped using this product.
Definitely disappointed overall, would not buy again.

*Rating is in the middle because it used to be good, now mediocre for the price*
I have been using this product for over a year and was really content up until recently. Was very happy with the taste and texture of the shake, went great with PB or in my morning oats I was using at least 5lbs a month.
Recently, the product has seemed to nose dive in quality(taste, mixability even the powder itself looks different). keep in mind none of this product is anywhere close to printed expiry dates.
I contacted Nutrabolics and they accept no fault or offer any comp for the lackluster product. In correspondence they stated that nothing has changed and tried to shift blame to the supplier(All tubs were from their official suppliers)

Directions For IsoBolic: Mix 1 scoop (31 g) of ISOBOLIC® in 8 oz - 10 oz/250 ml - 300 ml of ice cold water or milk and shake for a few seconds. Vary the amount of liquid to achieve desired flavor and consistency. Drink 1-3 servings daily or as needed to satisfy your protein or muscle building requirements. For best results, combine with a diet and exercise program.

Warnings: For adult use only. Keep out of reach of children. Consult your physician before using the product if you have any medical condition. Do not use if you are pregnant or nursing.
